    Do You Work Outside London?

    Yes. While the majority of our interior joinery, garden rooms, and renovation projects are located in South London and Greater London, we are happy to discuss projects further afield depending on scope and scale.

    If you’re unsure whether we cover your area, simply get in touch — our team will be happy to confirm availability and discuss your project.

  • We offer flexible pricing based on project type and complexity. After an initial conversation, we’ll provide a transparent quote with no hidden costs.

  • Collaborative, honest, and straightforward. We're here to guide the process, bring ideas to the table, and keep things moving.

    From the initial design stage, giving you CAD drawings to help realise your plans, through to the installation of your joinery/garden room/new living space, we encourage collaboration and communication from clients.
